Description

Technical Field

[0001] The present application relates to the field of conveying equipment, and in particular to a paper conveying system. Background Art

[0002] In the paperboard production line, conveyor belts are generally used to transport paperboards. The widespread use of conveyor belts reduces the burden on workers and improves transportation efficiency. For stacks of paper, baffles are usually set on the conveyor belt. The distance between the baffle and the conveyor belt is only enough for one paper to pass through, so that the papers are transported one by one.

[0003] However, different papers have different friction coefficients and degrees of hardness. For softer papers and papers with larger friction coefficients, when the lower paper is conveyed, the upper paper may be wrinkled and damaged due to friction. Summary of the invention

[0004] In order to improve the paper conveying device and reduce the possibility of paper damage, the present application provides a paper conveying system.

[0005] The paper conveying system provided in this application adopts the following technical solution: A paper conveying system comprises a frame, wherein a paper separation assembly and a paper feeding assembly are sequentially arranged on the frame along the paper conveying direction, a support frame installed on the frame is arranged between the paper separation assembly and the paper feeding assembly, the paper separation assembly comprises a baffle arranged on the support frame, a support plate is arranged at one end of the baffle close to the frame, the support plate is located on the side of the baffle away from the paper feeding assembly, a cross beam is arranged at one end of the frame away from the paper feeding assembly, a supporting plate flush with the supporting plate is arranged on the cross beam, and a paper tearing piece located below the supporting plate is also arranged on the cross beam.

[0006] By adopting the above technical solution, a stack of papers is placed at the paper separation assembly and supported by the support plate and the support plate. Then the paper pulling member pulls the bottom layer of papers onto the frame. Then the paper feeding assembly drives the papers on the frame to move. This process is repeated to transmit the papers one by one, thereby reducing the friction between the papers and reducing the possibility of paper damage due to friction.

[0007] Optionally, the paper tearing member includes a supporting air duct arranged below the supporting plate, the supporting air duct is slidably connected to the crossbeam along the paper conveying direction, and a side of the supporting air duct close to the supporting plate is also provided with a plurality of retractable suction cups connected to the inside of the supporting air duct.

[0008] By adopting the above technical solution, when the paper tearing piece is working, the suction cup first extends and abuts against the bottom layer of paper, the suction cup sucks on the paper, and then the supporting air duct moves away from the supporting plate until the bottom layer of paper is separated from the supporting plate. Then the suction cup no longer sucks the paper and shrinks and becomes shorter. At this time, the bottom layer of paper falls onto the frame. Through the above steps, the paper is first separated and then conveyed, thereby reducing the possibility of paper wrinkles and damage.

[0009] Optionally, a driving member is provided between the supporting air duct and the crossbeam, and the driving member includes a pair of driving gears rotatably connected to the crossbeam, an annular driving rack connecting the two driving gears is provided between the two driving gears, a connecting plate connecting the driving rack and the supporting air duct is provided between the two driving gears, and a driving motor for driving the driving gears to rotate is provided on the crossbeam.

[0010] By adopting the above technical solution, the driving motor drives the driving gear to rotate, the driving gear drives the driving rack to move, and then drives the supporting air duct to translate through the connecting plate, so that the supporting air duct can be slidably connected to the crossbeam.

[0011] Optionally, the crossbeam is slidably connected to the frame, a positioning rack is fixedly connected to the frame, a positioning gear is meshed on the positioning rack, and the positioning gear is rotatably connected to the crossbeam.

[0012] By adopting the above technical solution, the positioning gear rotates and moves along the positioning rack, thereby driving the beam to move along the length direction of the positioning rack. Therefore, when conveying papers of different specifications, the distance between the beam and the baffle is adjusted, so that the support plate and the supporting plate can support papers of corresponding specifications, thereby improving the applicability of the equipment.

[0013] Optionally, limit plates are provided on both sides of the baffle, the limit plates are slidably connected to the support frame, and the two limit plates move toward each other, the upper ends of the limit plates are bent, and the upper ends of the two limit plates are inclined in a direction away from each other.

[0014] By adopting the above technical solution, the upper end of the limiting plate is bent, so that the paper can pass between the two limiting plates more easily, and the two limiting plates move toward each other, so as to regularize the paper stack, thereby allowing the paper to be transported neatly.

[0015] Optionally, the paper feeding assembly includes a groove opened on the frame and located below the baffle, a conveying roller is rotatably connected in the groove, and the groove is connected to a suction pipe.

[0016] By adopting the above technical solution, when the paper falls onto the frame, the suction pipe draws air into the groove, so that the paper is pressed onto the frame by negative pressure, thereby maintaining the stability of the paper. At the same time, the conveying roller rotates to continue conveying the paper forward.

[0017] Optionally, two parallel rotating rods are arranged up and down on one side of the groove away from the paper separation assembly, and the rotating rod is provided with multiple driving blocks. The driving blocks on the two rotating rods are arranged opposite to each other, and the opposite driving blocks clamp the paper.

[0018] By adopting the above technical solution, the paper is transmitted by the conveying roller to between the two rotating rods, and the driving blocks on the two rotating rods clamp and transmit the paper, providing forward power for the paper.

[0019] Optionally, the paper feeding assembly also includes multiple conveyor belts installed on a frame, the frame is provided with two parallel fixed rods, the fixed rods are provided with fixed blocks corresponding to the conveyor belts, a connecting rod is hinged on the fixed block, the fixed block is provided with a limit block for limiting the rotation angle of the connecting rod, and the end of the connecting rod away from the limit block is rotatably connected to a roller or a roller brush.

[0020] By adopting the above technical solution, after the paper passes through the driving block, it is transported by the conveyor belt, and then the roller and the roller brush press the paper onto the conveyor belt under the action of gravity. For paper of different thicknesses, the connecting rod rotates to adapt to paper of different thicknesses.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: A stack of paper is placed at the paper separation assembly and supported by the support plate and the support plate. Then the paper pulling member pulls the bottom layer of paper onto the frame. Then the paper feeding assembly drives the paper on the frame to move. This process is repeated to deliver the paper one by one, thereby reducing the friction between the papers and the possibility of paper damage caused by friction. When the paper tearing piece is working, the suction cup first extends and abuts against the bottom layer of paper. The suction cup sucks on the paper, and then the supporting air duct moves away from the supporting plate until the bottom layer of paper is separated from the supporting plate. Then the suction cup no longer sucks the paper and shrinks and becomes shorter. At this time, the bottom layer of paper falls onto the frame. Through the above steps, the paper is first separated and then conveyed, thereby reducing the possibility of paper wrinkles and damage. BRIEF DESCRIPTION OF THE DRAWINGS

This is repeated to deliver the paper one by one.

[0030] Limiting plates 12 are installed on both sides of the baffle 21. The limiting plates 12 are slidably connected to the support frame 11, and the two limiting plates 12 move toward each other. The limiting plates 12 are fixed to the support frame 11 by bolts. The upper ends of the limiting plates 12 are bent, and the upper ends of the two limiting plates 12 are inclined in a direction away from each other. The upper ends of the limiting plates 12 are bent, so that the paper can pass between the two limiting plates 12 more easily. The two limiting plates 12 move toward each other, thereby tidying up the paper stack, so that the paper can be neatly conveyed.
